Scorpaenidae are mostly marine fish,very few found in fresh and brackish water. The family have around around 45 different genera and 380 different species. They are mostly found in the India Ocean and the Pacific Ocean. Most of them lives in coral, tropical reefs and shallow waters, warmer areas. Not all of the family fish lives in the shallow water, small portion of the Scorpaenidae live deep as around 7,000 feet. Just like most of the coral reef fish are, Scorpaenidae have camouflaged body. Their characteristic reflects their name, they have sharp spine that can sting other organisms. Their spine are covered with venomous mucus just like how some other kind of fish are covered with the venomous mucus. Their body are covered with scales. Generally speaking, the Scorpaenidae family fish have different number of spines over the course of the body. Most known type pf Scorpaenidae are lionfish and scorpionfish. Lionfish have preorbital bone with 3 spines, spines and third below the diagonal; , big mouth, end position, oblique fissure. Mandible, vomer and jaw bone with villiform teeth group. Gill openings are wide, tetrabranchiate membranes without the isthmus, pre-opercular margin with 5 spines. Body are ctenoid scales, round head. On the side, there are about eight to nine dorsal fin, fin spines and rays of an anal fin; five to six pectoral fins, they are large, round, and are branched from the upper fin rays. There are about one to five pelvic, sub thoracic; caudal fin rounded truncate. Reef stonefish are extremely camouflaged, they could look exactly like a rock when hiding for predation. The spines of Scorpaenidae are hard and rough, some of their fin spines have poison, can cause serious pain, swells and fatal wounds. Some of ...

Some dive deep into the water, like a lionfish, bream, viviparous fishes of the family Scorpaenidae and Lake Baikal in some species can dive to 1000 ~ 4000 meters deep, some often floating in the upper, such as six line fish, and Lake Baikal fishes of the family. The fishes swimming are relatively slow, often hidden, not activities or bury the body in the sand, and the type of six line fish families peace Marmora subfamily is good at swimming.

Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,
As the pistol shrimp uses its powerful snapping craw as a weapon to hunt, it makes such a noise that it can even alter the sound transmissions of submarines. (BBCWorldwide, 2009) In the video clip “Pistol shrimp sonic weapon” it shows how this snapping shrimp uses its sonic weapon, which is a large claw that snaps to releasing bubbles. (BBCWorldwide, 2009) These bubbles are shot at the shrimp’s prey at such temperature that when their released they can reach the sun’s temperature for a instant. (BBCWorldwide, 2009) Although this pistol shrimp has a astonishing feature, its important to analysis the way this snapping shrimp uses its claw to create a load snap noise through cavitation bubbles and the fundamentals behind its claw regrowth from
An English naturalist Charles Darwin (1802-1882) developed a theory of biological evolution. He studied variation in plants and animals during his five years’ voyage around the world in the 19th century. Darwin studied hundreds of species, which he researches variations between locations. His theory states that all species of organism arise and develop through natural selection. Natural selection is the process of organisms that adapt to their surrounding environment, which tend to survive and produce more offspring. Killer whales are remarked to have evolutionary links from land dwelling organisms, millions of years ago. This paper will display the evolution and natural selection of the killer whale.
Another interesting fact about Lake Baikal is that more than 1,700 species of animals and plants live in the body of water. Of the 1,700 species, approximately two-thirds of those animals are unique to Lake Baikal. In other words, nearly sixty-six percent of Lake Baikal’s animals cannot be found in any other body of water in the world (Saving Lake Baikal). Species found in Lake Baikal include arctic grayling, Baikal sturgeon, and freshwater seal. Due to the huge selection and uniqueness of species in the lake many people do not know of or do not see numerous species that exist in our world. 1,700 different species in one lake is...
The story Sea Oak written by George Saunders is a compelling story about a male stripper, his aunt, sisters and their babies, who resides in a dangerous neighborhood. His only hope and aspirations to help move his family out of the Sea Oak environment are to rely on his unusual job. He copes with his dead Aunt who visits him in his dream. She explains her life struggle and why great things didn’t happen for her during her time living. When Aunt Bernie dies from panicking after a burglar breaks in, her body is discovered missing from the grave days after her death. Aunt Bernie, the peacemaker, pleads with the narrator about him stripping for women by earning $20. The family lives in apartment complexes where the money the male stripper earns,
Though food is everlasting in both the coral reef and deep sea, space is very limited. Organisms in both habitats have to compete for space and survival, having defense mechanisms to keep other species from killing out their kind. Some fishes in the coral reef hide in cracks and crevices along the rocks and corals to hide from their predators. Other fishes camouflage within the brightly colored corals to hide from predators, or even humans looking into their tank. The deep sea holds many small fish, but with large mouths. The large mouths and pointy teeth help the miniscule fish eat their prey, whi...
There’s No Real Good Guy In the movie, “Blackfish” we are exposed to the fact that the way orcas are treated at SeaWorld is worse than we are lead to believe. We see how they are forced to swim in tiny pools and how they can only be fed if they preform well. After seeing this it makes you feel like the only way to help these poor creatures is to jump on the animal activist wagon and to free all the whales like in “Free Willy”. But is that really the right way to go?
The morphology of whale sharks is mostly similar to aquatic fish species, but many specific traits help differentiate them from the rest. Whale sharks are the largest fish in the world and can reach a size of around 20 meters (Martins, C., and C. Knickle). This is often compared to the size of a school bus. The shark has a very large transverse mouth. They have 5 very large gill slits and have a larger first dorsal fin compared to the second one (Whale Shark). They have a distinctive spotted “checkerboard” pattern with stripes (Martins, C., and C. Knickle). It is not exactly known why they have this specific body marking. It is believed that the body markings act as a camouflage. The strange thing about whale sharks is that they have 300 rows of teeth that play no role in feeding (Martins, C., and C. Knickle).
The walking catfish has become known as a notorious and harmful indigenous species on the top 100 most invasive species list (Masterson 2007). The species is so harmful that is has been blacklisted by numerous states including the state of Indiana (Brogan 2003). This species has a certain trait that allows it to work its way throughout the regions in order to invade and reproduce. Due to the species ability to walk on dry land and also to survive long periods of time without food or water, it has made its mark as an invasive species (Masterson 2007).
Due to protonic natureconsists of protein, it is smooth and water resistant and it is the outermost thin layer.Meanwhile there is a propensity to mistake primary wall with the cuticle, but these are particular and distinctive structures botanical view. During their life cycle, at some stage, cuticle are presented in the air, usually consider a characteristic of cells [10]. The structure of the cuticle has been determined that it is often extremely thin as comparatively few plants. The general principles explained by Lee and Priestley that are appropriate to the cuticle. These substances primarily is in an oily film in the form of deposit, travel through the primary wall, later it shrinks to varnish-like cover known as cuticle. The state of combining and nature of the fat are significant in order to defining the kind of cuticle. For example, in comparison to sodium oils, potassium and magnesium, calcium salts of unsaturated fatty ac-ids having minor solubility. The comparative proportions of oils in a thinner cuticle bases in the soil can affect the cuticle’s thickness because oils are more

Goldfish are typically trouble-free pets for all the family to enjoy. Goldfish are one of the easiest of all fish to keep, but if they are to be kept in an aquarium you must remember that they are totally dependent on you for their welfare. A well cared for goldfish can live for eight years or longer.
Caterpillar’s revenues that are generated come not just from the United States but from many other countries they do business in . This means that they have to deal with different currencies. “Caterpillar is exposed to currency exchange rate risk because the firm operates in numerous countries and conducts bu siness in multiple currencies” (Downie, 2015) .
One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
